Abstract

Gold nanoparticles in the mid-nanometer size regime can undergo self-organization into densely packed monoparticulate films at the air-water interface under appropriate passivation conditions. Films could be transferred onto hydrophilic Formvar-coated Cu grids by horizontal (Langmuir-Schaefer) deposition or by vertical retraction of immersed substrates. The latter method produced monoparticulate films with variable extinction and reflectance properties. Transmission electron microscopy revealed hexagonally close-packed arrays on the micron length scale. The extinction bands of these arrays shifted by hundreds of nanometers to near-infrared wavelengths and broadened enormously with increasing periodicity. Large particle arrays also demonstrated extremely high surface-enhanced Raman scattering (SERS), with enhancement factors greater than 107. Signal enhancements could be correlated with increasing periodicity and are in accord with earlier theoretical and experimental investigations involving nanoparticle aggregate structures.

23 The number of adsorbates in a 30- m diameter spot was approximated by using the surface area of an ideally planar array of hexagonally close-packed particles, which has a surface roughness of 1.8 independent of unit particle size. If surfactant adsorption is assumed to be at 75% maximum coverage (ca. 2 nm2/molecule), the number of adsorbates contributing toward the Raman signal is estimated to be 6.3 × 108 molecules.
